SCOPE This Regulation covers new pneumatic tyres designed primarily, but not only, for vehicles in categories M1, O1 and O2.

7 1/ It does not apply to tyres designed for (a) the equipment for vintage cars (b) competitions. 2. DEFINITIONS For the purposes of this Regulation, "Type of pneumatic tyre" means a category of pneumatic tyres which do not differ in such essential respects as: The manufacturer; Tyre-size designation; Category of use (ordinary (road-type) or snow tyre or for temporary use); Structure (diagonal (bias-ply), bias-belted, radial-ply, run flat tyre); Speed category symbol; Load-capacity index; Tyre cross-section.

8 "Snow tyre" means a tyre whose tread pattern and whose structure are primarily designed to ensure in mud and fresh or melting snow a performance better than that of an ordinary (road-type) tyre. The tread pattern of a snow tyre generally consists of groove (rib) and/or solid-block elements more widely spaced than on an ordinary (road-type) tyre; "Structure" of a pneumatic tyre means the technical characteristics of the tyre's carcass. The following structures are distinguished in particular; 1/ As defined in Annex 7 to the Consolidated Resolution on the Construction of Vehicles ( ), (document as last amended by ).

9 E/ECE/324 E/ECE/TRANS/505 } Regulation No. 30 page 6 "Diagonal" or "bias-ply" describes a pneumatic-tyre structure in which the ply cords extend to the beads and are laid at alternate angles of substantially less than 90 to the centre line of the tread; "Bias-belted" describes a pneumatic-tyre structure of diagonal (bias-ply) type in which the carcass is restricted by a belt comprising two or more layers of substantially inextensible cord material laid at alternate angles close to those of the carcass.

10 "Radial" describes a pneumatic-tyre structure in which the ply cords extend to the beads and are laid substantially at 90 to the centre line of the tread, the carcass being stabilized by an essentially inextensible circumferential belt; "Reinforced" or "Extra Load" describes a pneumatic-tyre structure in which the carcass is more resistant than that of the corresponding standard tyre; "Temporary use spare tyre" means a tyre different from a tyre intended to be fitted to any vehicle for normal driving conditions but intended only for temporary use under restricted driving conditions; "T-type temporary use spare tyre" means a type of temporary use spare tyre designed for use at inflation pressures higher than those established for standard and reinforced tyres.
